Special PREPOL® calcining systems for different requirement profiles

In addition to assuring complete combustion of the fuel, the calciner has to function with great flexibility, in order to cope with the wide range of fuel grades used (from highly reactive to extremely unreactive). Today, great importance is placed on systems incorporating primary measures for emission reduction.

For such requirements thyssenkrupp Industrial Solutions has developed the PREPOL®-MSC-CC system in addition to the proven PREPOL®-MSC calciner. This system permits the use of unreactive fuels and simultaneously reduces the nitrogen oxide emissions.

The PREPOL® calciner programme offers a number of systems in order to optimally fulfill individual requirements with regard to operating reliability, product quality, flexibility and emission reduction.

PREPOL® Step Combustor (SC)

The PREPOL®-SC is the latest addition to this programme. It is a simple, reliable and safe combustion system for the process-integrated preparation of solid alternative fuels. It can handle feed material sizes of max. 300 x 300 x 20 mm without any problem.

Installed at the side of the calciner and above the calciner nozzle, the PREPOL®-SC significantly reduces the required amount of mechanical preparation of the fuels and assures high burnout rates through the long fuel retention time in the combustion chamber. A portion of the tertiary air serves as the combustion air.
